Abstract
This invention relates in part to processes for producing one or more substituted or unsubstituted 1,6-hexanediols which comprise subjecting one or more substituted or unsubstituted penten-1-ols to reductive hydroformylation in the presence of a reductive hydroformylation catalyst, e.g., a metal-organophosphorus ligand complex catalyst, to produce said one or more substituted or unsubstituted 1,6-hexanediols. The substituted and unsubstituted 1,6-hexanediols produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof, e.g., epsilon caprolactone. This invention also relates in part to reaction mixtures containing one or more substituted or unsubstituted 1,6-hexanediols as principal product(s) of reaction.
